Obj-C Dropbox Library crashes in iOS8.4

[Robert S.138]

I just released my iOS app updated to Dropbox API v2 using the Obj-C library through CoCoPods.  I works fine in iOS9.  But now I am getting calls that it crashes on start-up under iOS8.x.  Then I ran an iOS simulator with iOS 8.4 and it does indeed crash on start-up with 

dyld: Symbol not found: _NSURLSessionTaskPriorityHigh

A search of the source code shows this appears in only one place, in the Dropbox file  DBTransportClient.m.  The Obj-C library was supposed to be compatible with iOS8 and above.  What should I do?

By the way, I commented out the offending line in DBTransportClient.m and my app started up without errors.

Hi Robert, what version of the SDK do you have installed? This sounds like a bug that was fixed in version 1.1.1. Please make sure you're using the latest version, currently 2.0.6.

How can I check and how do I update?  (I am very new to CoCoPods).

The contents of the "Podfile.lock" file should tell you what you currently have installed.

You can control what version you get installed using the contents of your "Podfile" file. You can use this line to just request the latest version:

pod 'ObjectiveDropboxOfficial'

Run `pod update` to update the pods installed in your project.

Thanks.  I figured it out too.  I just ran

pod update

and it is updating from 1.0.11 to 2.0.6.
